Ha α Critical Value Illustration

1. p ≠ 0. 52 0.01

2. p > 0.35 0.10

3. p < 0.7. 0 0.05

4. p > 0.65 0.05

5. p ≠ 0. 46 0.01

Answer 1

1. p ≠ 0. 52 0.01

To determine the critical value, we use t-table.

Here we have two-tailed test, so the critical value for a=0.01 is z=+-2.576.

2. p > 0.35 0.10

Here we have right-tailed test, so the critical value for a=0.10 is z=1.282.

3. p < 0.7. 0 0.05

Here we have left-tailed test, so the critical value for a=0.05 is z=-1.645.

4. p > 0.65 0.05

Here we have right-tailed test, so the critical value for a=0.05 is z=1.645.

5. p ≠ 0. 46 0.01

Here we have two-tailed test, so the critical value for a=0.01 is z=+-2.576.
